1. A medical circuit comprising:
a medical tube comprising a first elongate member, the first elongate member comprising a wall, the first elongate member being spirally wound around a main lumen that defines a main gases flow path of the medical circuit, the first elongate member comprising a lumen, and the wall of the first elongate member separating the main lumen from the lumen of the first elongate member; and
a vent coupled to the first elongate member using a housing, the vent defining a gaseous passageway between the lumen of the first elongate member and atmosphere;
wherein, in use of the vent, the vent allows gaseous communication between the lumen of the first elongate member and atmosphere and substantially prevents ingress of liquid into the lumen of the first elongate member.
